Overall quite impressed I think it works very well. Classic BMW side profile. I hate these damn pedestrian safety laws but the hood doesnt look too bad actually; it flows better than sedan. Also, I wish they didn't stretch roofline for fastback look but they did make a good of it.

there are only 3 things I don't like about this: the side vents, the rear diffuser (too exaggerated IMHO, but the production version is probably going to be a lot more subdued) and that it's called the 4 series...

overall, though, I'm very impressed! I think it looks really good, the proportions are just right. And this front end makes a lot more sense in the coupe than it does on the sedan.

But considering that this 4 series is probably going to be priced higher than the 3 series, they could've changed the interior design to differentiate them a bit further... I do like the materials, though!
